Herbicide technique: pre-emergent herbicides only through weeds radicle, coleoptile or hypocotyl absorb bensulfuron methyl, and kill weeds bensulfuron methyl manufacturers, after the emergence of weeds in use, generally without herbicidal effect or herbicidal effect is very low. Post-emergent herbicide can also use safe and effective in certain growth stages of weeds or crops. Increase herbicide effectiveness: soil treatment herbicide is absorbed, along with large amounts of water will be transporting up, enabling inhibition of photosynthesis, can significantly improve the herbicidal effect. Therefore, the use of herbicide bensulfuron methyl wholesalers, the greater the air humidity, the herbicidal effect more obvious; on the contrary, will reduce the herbicidal effect.
